History moves in contradictions. The skeleton of historic existence, the economic structure of society, also develops in contradictions. Forms eternally follow forms. Everything has only a passing being. The dynamic force of life creates the new over and over again — such is the law inherent in reality.

But to everything in this world there comes an end; there even comes an end to the torments suffered in those intermediate states of transition when the last secret tear of one's soul is bitterly swallowed, and the crisis passes, resolving itself into some new sort of phase, which even as it comes into existence is fated in turn to pass away, to disappear in the eternal changing of the times and seasons.
